The field of exoplanet atmospheric characterization has recently made considerable
advances with the advent of high-resolution spectroscopy from large ground-based …

High-resolution spectroscopy (R≥ 25,000) has recently emerged as one of the leading
methods for detecting atomic and molecular species in the atmospheres of exoplanets …

We explore how well spectra from the James Webb Space Telescope (JWST) will likely
constrain bulk atmospheric properties of transiting exoplanets. We start by modeling the …

Spectral retrieval has long been a powerful tool for interpreting planetary remote sensing
observations. Flexible, parameterised, agnostic models are coupled with inversion …

Extremely irradiated hot Jupiters, exoplanets reaching dayside temperatures> 2000 K,
stretch our understanding of planetary atmospheres and the models we use to interpret …

The present-day envelope of gaseous planets is a relic of how these giant planets originated
and evolved. Measuring their elemental composition therefore presents a powerful …

We report high-resolution spectroscopic detection of TiO molecular signature in the day-side
spectra of WASP-33b, the second hottest known hot Jupiter. We used the High Dispersion …

We present the first detection of atomic emission lines from the atmosphere of an exoplanet.
We detect neutral iron lines from the dayside of KELT-9b (T eq∼ 4000 K). We combined …

Context. Recently, the He I triplet at 10 830 Å was rediscovered as an excellent probe of the
extended and possibly evaporating atmospheres of close-in transiting planets. This has …

The nature of the thermal structure of hot Jupiter atmospheres is one of the key questions
raised by the characterization of transiting exoplanets over the past decade. There have …
